Century-old solvent linked to elevated Parkinson's risk

Trichloroethylene (TCE), a century-old solvent once used in dry cleaning and various household products, is linked to a roughly fivefold increase in Parkinson's disease risk, with both occupational and environmental exposure. Researchers from the University of Rochester Medical Center say the long latency between exposure and symptoms can obscure cause, and historical cases like Camp Lejeune highlight community risks. Public health actions include the EPA banning TCE manufacture/import and processing, with risk evaluations and regulations continuing to guide safeguards.
